To all 'whomit may concern:

Be it known that I, OLrvEu EDWARD Merv ,RELL, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Desiccating Apparatus, of which the following, taken in connection. with the acco npaying-drawings, is a full, clear, and exact description. i

This invention relates to an apparatus tor obtaining the solids from organic liquids,

i the formof a substantially dry powder, w ich may be returned again to its original li liid form by the'addition of a suitable a cunt of water, without the loss of the dis- 1 tinguishing characteristics of the original;

li uid lhe invention is especially applicableto.

Mid intended for the drying of organic} liquids having a. high moisture-content, such 3 as milk,and eggs. If milk is treated, it may; Tbein its original condition, or the cream may 'befirst removed; and, in either case, the

milk (whole or skimmed) may :be condensed or concentrated before subjecting it-to the desiccating operation. Cream may also be I dried to a powderhy the new process.

The organic liquid is subjected to the in timate action of a whirling current otmois ture-absorhing air SUiilClGIlt in quantity to take up and carryofi the moisture-content of the liquid, the spirally forward motion imparted to the air current causing the air to disintegrate theliquicl and break it up into excessively 'fine particles in the nature of ga'oloud ojr mist, with the result that the moisture is removed from the solids and absorhed'by the air in a practically instantaneous manner, leavingthejdry solids to collect i 40. ffiGphretelyiromthe moisture-laden air current." v -"Suitahlegapparatusfor carrying out the 'irooess 15' illustrated in the accompanyiiig ravyings, where'in- Figure 1 is a top plan of the apparatus partly in sectio n.
